HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 765,249, dated July 19,1904.

Application filed ch 21, 1903.

To all whom it may concern:

Be it known that I, SIMON J. MCDONALD, a citizen of the United States,residing at Detour, in the county of Chippewa and State of Michigan,have invented certain new and useful Improvements in Hose-Couplings; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to hose-couplings, and more particularly to anattachment adapted to fit over the end of a hose and lock the joint ofthe coupling proper received by the end 5 of said hose; and my inventionconsists of certain features of construction and combination of parts,as will be hereinafter fully described and claimed, reference being badto the accompanying drawings, which are made a part of this application.

The object of my invention is to provide simple thoughreliably-efficient means adapted to engage a portion of one member of ahosecoupling and prevent the same from being 5 blown out by the force ofthe escaping Water.

A further object, among others, is to provide means for readilyattaching and detaching my invention in its operative position upon theend of a hose.

3 Other objects and advantages will be made clearly apparent byreference to the accompanying drawings, which are made a part of thisapplication, and in which Figure 1 shows a side elevation of myinvention complete. Fig. 2 shows a similar view taken at right angles tothe showing made in Fig. 1. Fig. 3 is an end view of my hose attachmentas applied to use upon the end of a hose-section, while Fig. 4 shows my4 invention as blanked out of a piece of suitable sheet metal ready tobe bent into the desired form for fitting around the end of a hose.

Designating-numerals will be employed in order to conveniently refer tothe various details of my invention and cooperating parts, the samenumeral applying to a similar part throughout the several views.

Serial No.148,913. (No model.)

In materializing my invention I provide suitable clamping means adaptedto engage the part of the coupling contained in the end 5 O of the hoseand securely lock the samein place.

Referring to the numerals on the drawings,

1 indicates the end of a hose of the usual or any preferredconstruction, within which, as

is common, is inserted the stem of one member 2 of the coupling proper.The member 2 is provided upon diametrically opposite sides with-lugs 3,which may be readily formed in any preferred way, as by casting the samewhen the coupling member is formed, or suit- 66 able apertures may beprovided and said lugs may be threaded into said apertures, as will beobvious.

Designed to cooperate with the lugs 3 is the ring-like member 4:, havingan opening of 5 proper size to fit snugly around the member 2, suitablerecesses 5 being provided on the inner edge of the ring or collar 4,whereby when the coupling member 2 is turned said recesses 5 willregister with the position of 7 the lugs 3, carried by the couplingmember, and thus permit such member to be withdrawn from its seat in theend of the hose.

In Fig. 3 I have indicated by dotted lines the position of the lugs whenthe member 2 is turned into a locked position. I prefer to form thecollar or ring section 4 and the anchoring-plates 6 all integral or fromone continuous piece of suitable sheet metal, as more clearly shown inthe blank presented in Fig. 4, said anchoring-plates 6 being alsoprovided with integral extensions or ears 7, having suitable apertures8, through which when a pair of said ears are bent or extended outwardparallel with each other they may be readily se- 5 cured, as by thelocking-bolts 9 extending through said apertures.

By means of the construction hereinbefore described it is thereforeclearly apparent that the retaining-ring 4: and the plates 6 may be 9reliably anchored in position upon the end of the hose, and therebyinsuring that the coupling member 2 will be very securely retained inits seat in the end of the hose.

By reference to Figs. 1 and 2 it will be seen that I have providedsuitable seats in the ring or collar section 4, adapted to more securelyengage and retain the lugs 3 in place when adjusted therein.

It is obvious that the anchoring-plates 6 may be formed of proper size,so as to practically inclose one-half of a contiguous part of the hose,thereby disposing the ears 7 very close to each other, and, ifpreferred, said ears may be caused to overlap each other and be solderedin place, leaving the ears upon the opposite side only to be secured bylocking-bolts.

It will be understood that the ear-sections 7 may be made very small insize, so as to accomplish a reliable performance of their ofiice and yetpresent very little obstruction or impediment to the free use of thehose.

While I have described the preferred combination and construction ofparts deemed necessary in materializing my invention, I wish tocomprehend such equivalents and substitutes as may be considered asfalling fairly within the scope of my invention.

I/Vhat I claim as new, and desire to secure by Letters Patent, is

1. In a hose attachment, the combination with the hose and a couplingmember 2 having lugs 3, of a ring-like member 4 having recesses adaptedto receive the lugs 3 and also having seats 10 formed by bending aportion of the surface of the ring-like member outwardly, and atdiametrically opposite points to the recesses whereby when said lugsenter said seats said member 2 will be held against casual rotation,anchoring-plates formed integral with said member 4, having aperturedears and means to clamp said plates upon the hose, substantially asspecified and for the purpose set forth.

2. The herein-described hose attachment comprising the combination witha hose and a coupling member having lugs upon opposite sides, of ananchoring-collar adapted to fit around the end of the coupling member,said collar having recesses in its inner edge adapted to receive saidlugs; anchoring-plates adapted to encircle the end of the hose and earsextending from said plates, said collar, anchoring-plates and ears beingformed from one continuous strip of metal and means to draw said earstogether, whereby said plates will be locked to the hose, substantiallyas and for the purpose'set forth.

3. In a hose attachment the combination with the hose and a couplingmemberQ having lugs 8, of an anchoring device formed entirely of onepiece of material and comprising a ring-like member 4 having recessesadapted to receive the lugs 3 and also having seats 10 formed by bendinga portion of the surface of the ring-like member outwardly, whereby saidmember 2 will be held against casual rotation when the lugs 3 enter saidseats, semicircular anchoring-plttesG extending at right angles to saidring-like member adapted to surround and grip the interposed hose, earscarried by each plate having registering orifices therein and boltsadapted to enter said orifices and draw said plates toward each other toclamp the hose, substantially as specified and for the purpose setforth.

4. The herein-described hose attachment comprising the combination withthe hose and a coupling member having lugs upon opposite sides, of ananchoring-collar adapted to fit around the end of the coupling members,said collar having recesses in its inner edge adapted to receive saidlugs; semicircular anchoring-plates 6 connected to said collar and meansto lock said plates to the hose, substantially as and for the purposeset forth.

5. In a hose attachment, the combination with a hose and a couplingmember having lugs, of a ring-like member having recesses and seats toreceive said lugs said seats being at diametrically opposite points uponsaid ring-like member from the recesses and formed by bending a portionof said ring-like member outwardly, a pair of anchoring-platessemicircular in cross-section, each plate being of a size to practicallyinclose one-half of a contiguous part of a hose, one end of said platesbeing reduced in size and formed integral with the ringlike member, apair of cars upon each meeting edge of said plates having registeringopenings therein, and bolts fitting said openings and adapted to clampsaid plates to the hose, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

. SIMON J. MCDONALD.
